If in Bohr's model, for unielectronic atom, time period of revolution is represented as `T_(n,z)` where `n` represents shell no. and `z` represents atomic number then the value of `T_(1.2) : T_(2.1)` will be :-

A

`8:1`

B

`1:8`

C

`1:1`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
Radial node `=(n-l-1)`
Angular node `= l`
`4s, 5p_(x), 6_(dxy)` having 3 radial node. Angular node in all `s` orbital in zero.
